Hello all,
Traditionally, the capital form of the German sharp S (U+00DF ß) was
"SS". More recently, a capital sharp S (U+1E9E ẞ) was added as a
secondary alternative, but U+00DF’s uppercase mapping was left
unchanged.
However, it seems that official German orthography, as of 2024, now
considers ẞ to be the preferred uppercase mapping, with SS as the
secondary alternative. From

page 48:
> E3: Bei Schreibung mit Großbuchstaben ist neben der Verwendung des
Groß buchstabens ẞ auch die Schreibung SS möglich: Straße –
STRAẞE – STRASSE.
e.g.
> E3: When writing in capital letters, in addition to using the
capital letter ẞ, it is also possible to write SS: Straße –
STRAẞE – STRASSE.
However, changing U+00DF’s uppercase mapping from SS to U+1E9E at
this juncture would violate Unicode’s case pair stability guarantee.
I am not a German speaker, and have no opinion on what, if anything,
should be done about this. But I thought it best to raise the issue for
discussion.
